This invention relates to :contractorsi equipment and more especially to hoist sklps and their scaii'oldsx f I 1 An object of this invention is to provide a scaffold of sectional form'whose parts may, be readily set up and lat'endismantled for repeated re-'use-, and toprovide a scaffold ap-.: paratus having an adjustableltop or unloading'deckp i g 1 A; further object is to provide 'a skip-scaffold anda skip operative'th'erein and of adjustable form so as to vary capacity and be adaptable as a platform 'for carrying-loads 1 ofconstruction materialandfor arrangement 1 horizontally as an elevatorfor Wheeled vehicles. 1; Numerous additional objects,"; -advantages and features of construction and arrange ment, and detailsofmeansvvill-be made mani 2 fest in'lthe ensuing description of the here; with illustrative embodiment; itbeing understood that fmodifications, variations and adaptations may be resorted to Within the spirit, scope and'principle of the-invention l as-it is hereinaftermore directly claimed;

Fig. 20, is a detail showingan adjustable connece0 1 Theinvention includes a scafl'oldstructure comprisingrarear pair of spaced and con nected poles orstandards Sand a pair of p spaced guides G; the-latter being spaced less '65 than and in advance of'theformer, Fig.8, and forming runways for averticallymovable ,skip'or hoist 1 f v i In Fig ll the standard isshovvn as includinga number of tubular sections 2, and, if needed, subsections 3, all havingrigid brack ets orj crows-nestsft at suitable pitch, and also having,'on=their lower ends, fixed sockets 5 to receive abutted sections of the'standard as erected. i 7 5 of superimposed, channel iron segtions 6 and subsections '7, the former havingoint sockets 8-fixed,ion"-their upperendsrfor' added subsections 7 which may have sockets s on either so I end or none so that 'a proper length of guide maybe set upto; a coordinate standards;

"The guide 'sections(including the shorter subsections) have the side Walls offthe channels converged as clearly shown in Fig. 5, s5 andthe erected guideparts'forma smooth .runvvay for the shoes or runners 10 attached to. skip "frame part s 'lljvvhich are upright and transverselyiconnected by top and bot tom bar's 12%13. "Onthe top bar 12 is pivoted 90.

ous angles to the vertical frame andthis'is provided for by adjustable braces 24whose lower ends are hinged at 25 to the bottom bar 13 of hoist frame the braces 22* also being extensible. 5

When desired-a frontextension floor 26 is hung inthe channel joists15 by meansof horns 27 sliding, thereinto. and resting on loops '28 to which the braces 24are attacl1ed.

. The hoist is provided with anap ron29 hinged to be thrown over the top of its guides G when the hoist is used forelevatingbulk material, as lumber, lathand otherstructural parts.

The'front'guides G and the rear standards S are connected by foot irons 31-, Fig. 8,fand also by transverse tie-bars 32, Fig.9, which havefangle-iron arms '33 Fig. 7,"with dowel pins 34 to set in pin holes: 35 in the flange or top body of the crows-nest. 'f A On the forward ends ofthe brace arms 33 are socketsl36 to embracecon'ti'guous sections or units 6 7 of the guides G, thus staying them in vertical position and proper gage for the skip runners. I p The arms 33 of the scaffold have thrust bars33 adjustable to abutthe near wall W inrelation to which the scaffold is set up and vertically heightened section by. section as the wall is laid. j

'Material elevated or vehicles (wheel-barrows) may be put oil the hoist at anylevel or f carried to the top of the scafiold and dumped or run onto atop deck structure which'is carried by a topfgirde'r-or headerin'cluding a pair of L-irons 4O fixed' in spaced? relation on the crown-irons 3O and'receiving slip hinge leaves 41 pivoted at 42 in the ends .of sets of deck joists 43 which; are inverted channel irons. On these are fixed transverseajoists 44chavingouteturned webs 45 on which is secured a suitable-floored which may have protective guard strips l7 to receive the shock of "heavy building iron'or lumber I dumped ofi theskip.' j j 1 .Hanging from the joists A3 are links 48 and these carry brace spiders 48 on which are pivoted adjustable braces 4:9.whose outer ends are connectedto-straps'50 on theouter edge of the main-deck46. A swinging leafdeck 51 ,is hinged at 52-to the main'deck46. and has floor means is adapted to beset at vari-' so that-theapron29 .canbe swung ers 43- 43 when these are hinged at 42 t the header elements. I

The end or extension decks 46 have hooks 57, Fig. 18, to be applied, at will, to the end girders of deck 51 which have slots 58 for the hooks. Thus the end decks may be installed either onthe ends of themaindecks-or on the 7 ends of. the leaf 51 as runways'therefrom. In Figure 16 the decksandthe skip are set for service of wheel barrows and the like. '5" Thedeck braces 49 areradial to the spiders 4:8, as seenin Fig. 1. V

Any appropriate hoisting rig and tackle 60Vmay be;employedto run the skip. The top deck ha's'pivoted, adjustable legs 61and62 to be dropped into place in the building structure as may bene'eded in various uses of the apparatus 7 I '1 1 Fig, 20 'sh'ows'the skipafloor members 15 as adjustably bolted. to a hing-ed section 15 allowing thefloor to be adjusted outwardly down flat.
